Given numbers are 349, 170, 780, 636

The list of prime factors of all numbers are

Prime factors of 349 are 349

Prime factors of 170 are 2 x 5 x 17

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 636 are 2 x 2 x 3 x 53

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 349, 170, 780, 636

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(349, 170) = 59330

GCD(349, 170) = ( 349 x 170 ) / 59330

= 349 / 170

= 349

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 349, 170, 780, 636 is 1
